Description

Technical Field

[0001] The invention relates to the technical field of mining, and in particular to a ceramic particle wear-resistant plate structure and a preparation method thereof. Background Art

[0002] In the mining industry, the mass of the ore is large, and the impact and friction in the transfer link during the transportation process are particularly severe. The current market solution is to use highly wear-resistant high-manganese steel plates (manganese 11%-14%). The wear coefficient of manganese steel is 10 times that of ordinary carbon steel, but it still needs to be replaced frequently. In the industry, blind holes or through holes are left in manganese steel, and ceramic particles with better wear resistance are embedded in the holes using adhesives to increase the service life of wear-resistant workpieces; However, there are still many problems. First, the use of adhesives is prone to fall off due to the impact of stones and ores during use; second, ceramics are relatively brittle, and the use of adhesives can easily cause the ceramic particles to collide with the manganese steel substrate, resulting in the breakage of the ceramic particles; third, the holes and ceramic particles on the market now all have circular cross-sections, resulting in large gaps between the ceramic particles. When used for a long time, the manganese steel plate in the gap will wear out, causing the ceramic particles to leak out, resulting in the ceramic particles falling out due to force and losing their effect.

[0003] The existing single high manganese steel plate has low wear resistance and the ceramic is fragile, which affects the quality of ore processing. Therefore, a ceramic particle wear-resistant plate structure and a preparation method thereof are proposed to provide a set of ceramic particle wear-resistant plates with high ceramic coverage and wear resistance, as well as good seismic buffering and service life for ore conveying and processing equipment. Summary of the invention

[0004] In response to the problems in the prior art, the present invention provides a ceramic particle wear-resistant plate structure and a preparation method thereof to provide a set of ceramic particle wear-resistant plates with high ceramic coverage and wear resistance, as well as good seismic buffering properties and service life for ore conveying and processing equipment.

[0005] The technical solution adopted by the present invention to solve its technical problems is a ceramic particle wear-resistant plate structure and a preparation method thereof, comprising a high manganese steel plate, a high manganese steel frame, ceramic particles and a rubber filling structure, the high manganese steel frame is connected to one side of the high manganese steel plate, the rubber filling structure is arranged in the high manganese steel frame, and the ceramic particles are arranged in several groups and are buried in the rubber filling structure at equal distances.

[0006] By adopting the above technical scheme, a ceramic particle wear-resistant plate with high ceramic coverage and wear resistance, as well as good seismic buffering and service life is obtained through an assembly consisting of a high manganese steel plate, a high manganese steel frame, ceramic particles and a rubber filling structure.

[0007] Specifically, the ceramic particles are of a hexagonal structure, and the ceramic particles filled in the irregular inner edge of the high manganese steel frame are of a polygonal shape close to the inner edge of the high manganese steel frame.

[0008] Specifically, the rubber filling structure includes a bottom rubber layer, a gap rubber layer and a surface rubber layer, and the bottom rubber layer, the gap rubber layer and the surface rubber layer are all elastic cement.

[0009] Specifically, the bottom rubber layer is applied to the bottom of the high manganese steel frame, the gap rubber layer is filled between the ceramic particles, and the surface rubber layer is applied to the top of the ceramic particles.

[0010] A method for preparing a ceramic particle wear-resistant plate structure, specifically comprising the following steps: Step 1: Weld the high manganese steel frame to one side of the high manganese steel plate; Step 2: Select the required number of hexagonal ceramic particles according to the area of ​​the inner cavity of the high manganese steel frame, and select polygonal ceramic particles with a shape similar to the edge of the inner edge of the high manganese steel frame; Step 3: first apply a layer of elastic glue to the bottom of the high manganese steel frame to form a bottom rubber layer, then vertically adhere the hexagonal ceramic particles to the bottom rubber layer in sequence, and then fill the periphery of the hexagonal ceramic particles with polygonal ceramic particles until the high manganese steel frame is fully covered, and the surface of the ceramic particles is coated with elastic glue to form a gap rubber layer, and then apply a layer of elastic glue to the top of the ceramic particles to form a surface rubber layer; Step 4: Dry the coated elastic putty, and connect the ceramic particles with the high manganese steel plate and the high manganese steel frame based on the elastic putty to obtain a ceramic particle wear-resistant plate.

[0011] Specifically, the elastic putty is prepared by mixing an organic silicon polymer compound, a filler, an anti-compression agent, a plasticizer, a heat stabilizer and a flame retardant, wherein the ratio of the organic silicon polymer compound, the filler, the anti-compression agent, the plasticizer, the heat stabilizer and the flame retardant is 80:2:3:2:1:3; The silicone polymer compound is methyl vinyl phenyl silicone rubber, the filler is ABS, the compression agent is glass fiber, the plasticizer is high-density polyethylene, and the heat stabilizer is PET.

[0012] Specifically, when one side of the high manganese steel plate is a through-hole structure, a layer of elastic glue is laid on the back of the ceramic particles, and the ceramic particles are bonded to the through-hole structure of the high manganese steel plate through the elastic glue. If it is used for a flow channel plate, it is designed as an outer frame high manganese steel plate, and the elastic glue in the middle is used as a binder to bond the ceramic particles to the outer frame high manganese steel plate.

[0013] The beneficial effects of the present invention are as follows: the binder is changed to rubber, which has a certain flexibility and provides better impact resistance; the hole positions of ceramic particles and manganese steel plates can be designed to be regular hexagons, so that the ceramic particles have a higher coverage rate; if the manganese steel plate is designed to be a through hole, a rubber layer will be laid on the back of the wear-resistant part until it has a seismic buffering effect; if it is used for a flow channel plate, it is designed as an outer frame high manganese steel plate, and elastic glue in the middle is used as a binder to stick the ceramic particles to the outer frame high manganese steel plate. To ensure the density of the ceramic particles, regular hexagonal ceramic particles are usually used, and continuous irregular gaps are filled with ceramic particles of other shapes, so as to obtain a ceramic particle wear-resistant plate with high ceramic coverage and wear resistance, as well as good seismic buffering and service life, thereby solving the problems of low wear resistance of the existing single high manganese steel plate, fragility of ceramics, and impact on ore processing quality.
